Although the structure of mould may be ever-changing because plastics variety and performance, the shape of plastic products and the type of structure and injector etc. are different, basic structure is consistent.
Mould mainly is comprised of running gate system, thermoregulating system, forming part and constitutional detail.Wherein running gate system and forming part are and the direct contact portion of plastics, and change with plastics and goods, are the most complicated in mould, change maximum, require processing fineness and the highest part of precision.
Running gate system refers to that plastics enter runner section before die cavity from nozzle, comprise sprue, cold slug well, runner and cast gate etc.Forming part refers to consist of the various parts of article shape, comprises cover half, dynamic model and die cavity, core, curved lever and exhaust outlet etc.
Can accurately align in the matched moulds process in order to ensure fixed half and moving half and put in place, in mould, guiding parts must be set, guiding parts commonly used is comprised of guide pillars and bushes.In the actual conditions of producing, the phenomenon of wall thickness deviation often appears in injecting products, and defect rate is higher, causes raw-material waste, thereby has improved production cost.
The utility model content
For solving the deficiencies in the prior art, promote between dynamic model and cover half and align accuracy, the utility model provides a kind of injection mold with positioner.
A kind of injection mold with positioner, comprise the dynamic model and the cover half that cooperatively interact, described dynamic model and cover half are provided with the positioner that cooperatively interacts, and described positioner comprises the locating piece that is arranged on dynamic model, and are positioned on described cover half and the detent that matches with described locating piece.
When injection moulding, fixed half and moving half closed formation running gate system and die cavity, during die sinking, fixed half and moving half separates in order to take out moulded products; Align the quality that accuracy directly affects moulded products when dynamic model and cover half are closed, the utility model arranges positioner on the face that fits of fixed half and moving half, and act on simultaneously with existing guiding parts, make fixed half and moving half aligning in closing course, promote the Forming Quality of injection moulding.
As preferably, described dynamic model is provided with the holding tank for fixing described locating piece.
The locating piece interlocking is in the holding tank of dynamic model, and shape and the locating piece of holding tank adapt, and this holding tank is used for the position of stationary positioned piece, prevents that locating piece becomes flexible or the position changes in the process of opening or closure.
As preferably, described locating piece comprises:
Be fixed on the pedestal in described holding tank;
Be positioned at the projection of the bar shaped on described pedestal.
Locating piece of the present utility model is comprised of pedestal and projection, and pedestal is the installation position of locating piece, and projection is the position point of locating piece.
As preferably, described pedestal and projection are structure as a whole.
Pedestal and projection are structure as a whole, and make the intensity preferably that has of locating piece, and locating piece should be wear-resistant simultaneously, reduce the frequency that locating piece is changed.
As preferably, described pedestal is strip, and described projection is positioned at the middle part of this base top surface and arranges along described pedestal length direction.
Strip is the preferred a kind of embodiment of pedestal, and pedestal of the present utility model can also be set to other shape, and projection is also strip simultaneously, further the positioning accuracy of lifting positioner device.
As preferably, the degree of depth of described holding tank and the thickness of described pedestal adapt.
Whole pedestal embeds in holding tank fully, only has the side of the outstanding dynamic model of projection, makes positioner of the present utility model not affect applying degree between dynamic model and cover half.
As preferably, be embedded with the groove seat on described cover half, described detent is positioned at this groove seat towards a side of dynamic model.
Detent is not directly to be arranged on cover half, but is positioned at the groove seat that is inlaid in cover half, and the advantage of design is like this, even positioner in use produces wearing and tearing, for dynamic model and not impact of cover half, the positioner that more renews gets final product, and can save production cost.
As preferably, described groove seat is strip, and described detent is positioned at the middle part of groove seat and arranges along described groove seat length direction.
Detent should adapt with the shape of projection, cooperatively interacts in the process of both using, and the performance positioning action.
As preferably, described positioner is four, and four positioners are in the surrounding of the die cavity of injection mold.
Positioner of the present utility model is four, and is arranged in the surrounding of the die cavity of injection mold, compares single positioner, arranges that simultaneously four positioners can further promote positioning accuracy, improves the Forming Quality of product.
The utility model is simple in structure, and is reasonable in design, promotes fixed half and moving half and aligns accuracy when closed by adding positioner, thereby improve the moulding qualification rate of product, reduces production costs.
